As architect David Vincent, Roy Thinnes spent a couple of years during the ’60s feeling as though a significant percentage of the population was out to get him…but as the old saying goes, it’s not paranoia if they really are out to get you, and “The Invaders” most certainly were out to get David Vincent. It’s been quite some time since the series went off the air, however, and it’s gotten precious little airplay in the States in recent years. (Although the 1995 revival is best forgotten, in the absence of the original, we did at least get a series that resembled it at various times: “The X-Files.”) At long last, CBS-Paramount has made the decision to release “The Invaders: Season 1” on DVD, and the set – released on May 27th – features new episode introductions by Mr. Thinnes and a new interview with him. As it happens, we had an opportunity to interview him as well, and in addition to his work on the classic sci-fi series, we also asked him about some of the upstanding films on his resume.
